We recommend changing sediment filters when they become visually dirty or there is a noticeable drop in pressure. Change carbon blocks every 6-12 months depending on use. This kit does not include a membrane filter as they need replacement every three years or so, depending on water and set up.

I have every reason to believe that this is a very solid product at a really decent price.By bilferdon 3/31/2015

First of all, it came with plenty of DI resin (I had to throw a little bit away after packing it well.) Made in USA, which is typically a really good thing. My TDS meter reads 000ppm. The price is right. It just seems like a really good value. The filters seem high quality to the touch. I might be a little bias because I pick it up in person. I haven't really seen what it costs to ship under $175.

"This kit does not include a membrane filter as they need replacement every three years or so, depending on water and set up."

If you read to the end of the listing, you will see that it does not include the membrane filter. Why is that? Well, the membrane filter needs to be replace every 3 years or so. The other filters are replaced much more frequently . . . every 6-12 months. I've been using a RO/DI filter for approximately 2+ years and have used this particular replacement kit each time. It worked great when I had a 150 gallon saltwater tank. I've gotten out of saltwater and am now using RO/DI water in my Cichlid tank. This replacement kit has worked well for my needs.

This Replacement Filter Kit for my RO/DI system was everything I needed, and we've ordered it every single time when replacement was due. The kit shipped quickly, and was easy to understand and use. The how-to video's verified that we replaced everything correctly and with the DI Resin having a little extra, we were a little nervous that we did something incorrectly. BRS confirmed we did everything correctly, and a little excess was okay. Again, the BRS recommended replacement kit was much easier than ordering each piece separately!!

great for replacing my rodi filtersBy Kevinon 8/23/2014

it came with perfect instructions very simple to switch out filters but
i'm giving this filter replacement 4 stars because i believe it should come with the di resin sponges. if you read this i suggest you buy the replacement di sponges or maybe bulk reef should add them to this package.

My system was not used for a long time and I thought it would be best to change everything out. BRS has made it really easy to buy these rather than searching the web for each part separately. Really simple and ready to use. Videos from the site helped a lot.

In your opnioin about how often should the filters be changed. My TDS meter consistently reads 3 or 4 on the inlet prior to my DI resin and my DI resin needs to be changed about every 6 months so just wondering about the other filters.

Bulk Reef Supply
Hi Cal,
At the least the prefilters should be replaced yearly but it really comes down to usage. The carbon blocks are good for 6000g of total water (which is waste + product) and the sediment filters should be replaced when they become dirty/clogged. If either is clogged it would generally be visible by a decrease of water pressure on an RO/DI pressure gauge.

Good evening,
I own the standard RO unit with the DI, it's been roughly a year and I'd like to replace the necessary components in which need to be replaced within this time. Is this the correct kit to purchase? Thank you kindly.

Bulk Reef Supply
Hey Charlene,
If you have the 5 stage standard unit this would be exactly the filter kit you would need!

I have the 5 stage ro system. I need replacement filters but I am not sure exactly what I need. I see the kit for the five stage unit. The kit includes a bag of resin. What chamber is that for. Thanks.

Bulk Reef Supply
High there,
If you have our 5 stage RO/DI system then you would want the 5 stage RO/DI replacement filter kit. The bag is the bag of DI resin which replaces the DI resin on your RO/DI unit (the last stage).

1) I last purchased filters a few months ago. The sediment filter is a very very light brown. Yet, counter intuitively, I am seeing the pressure rise. I can easily hit 100PSI, unless I dial my kitchen sink back to about 25% output. Is this normal?

2) I've owned the entire unit for several years. In that entire time, I've never seen anything more than 1 TDS for the inlet and 0 for the outlet. No matter how long the unit goes without servicing, that seems unlikely. Is the meter faulty?

Bulk Reef Supply
Hi Steven,
1) Eventually that sediment filter will need changing as it gets very filthy, but if the pressure is increasing that's simply because the input water is. High pressure is a good thing but you do want to turn the sink down to keep it under 80.

2) The TDS meter on the unit measures the input of the DI (which is actually the output of the membrane) and the output of the DI. Considering your high water pressure and the fact that the water has already gone through 4 of the 5 stages of filtration, its not that unsual to see a number like 0-1 on the "in" side of the DI resin. Its likely just an indicator that your tap water was fairly low in TDS to begin with. The fact that the output number reads 0 and the resin hasn't turned entirely yellow also support this. Its a good thing, most folks would love to experience this!

I purchased the 5 stage drinking and reef filter kit and I was wondering why im missing a filter. I have a 5 stage drinking filter system with the one di filter that is separate from the drinking unit. The replacements came with a di package, 5 micron, purtrex 05 micron, chlorine taste and odor reduction, and a .6 micron. When should I replace the other filter and where can I purchase it?

Bulk Reef Supply
Hi Tiffany,
The filter that isn't included in the kit (which is different then this one, sounds like you have the 5 stage drinking and reef water replacement filter kit) is the 75gpd RO membrane. They only need to be replaced every 3-5 years, or often even much longer if you treat them nicely. They can be found right here in the future:http://www.bulkreefsupply.com/75-gpd-reverse-osmosis-membrane-dow-filmtec.html

I have the 5 stage plus system. I've produced about 10 gal a month since new April 2011. The TDS meter still reads 0 and pressure is good, but they're green, black, and brown. Do I need to replace my filters?

Bulk Reef Supply
Hey Chris,
Its best practice to replace the sediment filters and carbon blocks yearly if nothing else. Filters like the carbon blocks serve other functions like removing chlorine (which otherwise damage the membrane) and won't show up as TDS when they are depleted. Changing them on a regular basis ensures your not damaging the much more expensive membrane which otherwise should last 3-5 years or even longer.

Our filter kits feature some of the most widely used and trusted brands in the world including GE, KX Technologies and Pentek. The 10” filter size is the industry standard and will fit our systems as well as virtually every brand of RO system that uses similar looking carbon blocks. Most of the filters included in our kits are made in the USA, NSF Certified or WQA Gold Seal Certified and Manufactured using FDA-compliant materials.

*This is our recommended filter arrangement and we have found to be the best combination for the most common installations and water conditions. If you have something unique about your water supply or installation please contact customer service and one of our WQA certified water specialists will be able to assist you. Our onsite chat feature is the quickest way to receive advice but we are available to assist via the phone and email as well.
